s1mon posted a comment on discussion Runtime 🇬🇧
I don't know why the EtherCat fails, but what happens is: First I have only one 1WireMaster running on my Raspberry Pi and EtherCat is running fine. Then I'd like to add a 2nd 1WireMaster. Therefore I enable a 2nd GPIO Pin on the raspberry in the file "/boot/firmware/config.txt". dtoverlay=w1-gpio,gpiopin=4,pullup=0 dtoverlay=w1-gpio,gpiopin=23,pullup=0 To be able to use this 2nd 1WireMaster in Codesys Runtime I Adjust the CODESYScontrol.cfg file and add there: PlaceholderFilePath.2=/sys/devices/w1_bus_master2,...

yes sure. Thx for your support! This is the Codesys project stripped down only to my EtherCat and OneWire Configuration. The Project now contains only one OneWire Master on GPIO4.
-
All Sensors from the OneWire Master are assigned already to a seperate task with low prio (26) that runs with 1s cycle time. My EtherCat Task is running with Prio 1. It all works fine, until I adjust the CODESYScontrol.cfg or the CODESYScontrol_Usr.cfg files so that it supports a 2nd OneWire Master in the Codeys Runtime. If I change something in this config file and reboot my EtherCat Master stops working.

If I add "PlaceholderFilePath.2=/sys/devices/w1_bus_master2, $OneWire2$" to the CODESYScontrol.cfg I can use a 2nd OneWireMaster in the Codesys Runtime. But then my EtherCAT_Master is not working any more. Any Idea? Is there any instruction or documentation how a 2nd OneWire Bus Master can be used within Codesys Runtime on a raspberry pi 5?
-
Thx for the hint. It works if I add following line to the .cfg file. PlaceholderFilePath.2=/sys/devices/w1_bus_master2, $OneWire2$ Is there a documentation how to modify this config file? Will this be overwritten if I do an update of the CodesysControl Runtime?

Hi, I want to use two OneWireMaster on a Raspberry Pi5. I'm running Codesys Control for Raspberry Pi 64SL V 4.15.0.0. Under Linux I've configured two GPIOs for 1w bus usage on GPIO4 and GPIO27. Under Linux both masters seem to work fine and I can readout both sensors connected to both GPIOs. The two masters are 'w1_bus_master1' and 'w1_bus_master2'. In Codesys I've configured to OneWireMasters with the corresponding file paths. But in Codesys the 2nd onewiremaster "w1_bus_master2" doesn't work. Status...

Is there any update on this? When will CODESYS Control support GPIOs on Raspberry Pi 5?
